@Alixana Everything here is expensive, not just the juice. I prefer to imagine that SF is a foreign county and I am not spending American dollars, but some other currency with a generous exchange rate. $2500 for a small 1 br is insane, but 2500 quatloos? Not so bad!

Sadly, this is completely fake. The whole contraption is CG that is (badly) composited into the background shots. The shakey camera work helps disguise this but if you stabilize the images in Nuke (as a colleague did), you can see his shadow dancing all over the ground, the lack of parallax in the background plate, and the cloth sim flapping out of coordination with the motion of the person.

Also, it's just physically impossible. There's no way he can generate enough work to get liftoff with those wings by himself, and he is not carrying enough batteries to generate the power, either. I suspect it's a "viral" (ick) video for the brand of camera they're using.
